VESSEL AND OTHER CRAFT.

To all whom it may concern:

Be it known that I, PAOLO MAoeIo, a citi zen of the United States, and aresident of the city of New York, county of Kings, and State of NewYork, have invented certain new and useful Improvements in Vessels andother Craft, of which the following is a full, clear, and exactspecification.

My invention comprises means that may be operated to assist a vessel tokeep afloat in times of emergency.

It may also be utilized to raise a part of a vessel above the waterlevel that has sprung a leak, or has otherwise been injured.

My invention comprises a series of floats extending from the sides ofthe vessel, and are capable of being manned from the vessel to move themabout in the water at pleasure. They are rigidly connected to thevessel, in the sense that their buoyancy property is directlytransmitted to the vessel.

Referring to the drawings forming part of this speciflcationFigure 1 isa plan view representing a vessel equipped with four of my floats. Fig.2 is a side elevation of Fig. 1. Fig. 3 is a fragmental sectional viewthrough the plane m-w of Fig. 2. Fig. 4 is a fragmental plan viewshowing the mechanism devised on the inside instead of the outside ofthe vessel. Fig. 5 is a horizontal sectional view of a modification.Fig. 6 is an elevation of the modification shown in Fig. 5. Fig. 7 is asectional view of a float showing the interior construction, and Fig. 8is a modified form of float.

My invention consists broadly of the utilization of floats to giveadditional buoyancy to a vessel when occasion requires. The amount ofadditional buoyancy added will of course depend upon the number and sizeof floats. In the illustration shown in Fig. 1, four floats are shownand no particular heed is taken of the relative size of floats andvessel.

In the drawings Figs. 1, 2 and 3 show the float with the attendingmechanism secured to the side of the vessel on the outside thereof. Thevessel A is intended to represent any style and size of craft.Considering for the time, Figs. 1, 2 and 3, the float 1 is formedspherical and is made of any desired sheet metal. Fig. 7 shows a mannerof sup- Specification of Letters Patent.

porting it interiorly. Here a centrally located sphere 2 is providedwith radially extending bracing arms 8 which have their outer endssecured to the spherical shell of the float 1. Any other means forstrengthening the float may be used if desired. The float is mounted onan arm 4 by means of a universal joint. The joint is constructed byproviding lugs 5 on the float, and mounting it on the yoke 6, the lugsbeing passed through holes in the ends of the yoke to permit the floatto freely revolve, and as a securing means pins 7 are used. A socket 8is formed on the yoke for mounting it to rotate on the end of the arm 4.This freedom of motion of the float may save it from injury ifaccidentally struck. It will also permit it to roll upon the water andwill thus offer little resistance when the craft is moving, but at thesame time will possess its entire buoyancy power.

The arm 4 has a hub 9 formed upon its other end. This hub is secured ona shaft 10 mounted in journal box 11 formed in a housing 12. The housingand mechanism is preferably of bronze or other nonrustable material. Thehousing is secured to the side of the vessel as by bolts or rivets 13.Secured on the sh aft 10 and within the housing is a gear 14. The gearis in mesh with a worm 15 secured on a shaft 16. The shaft is mounted ina vertical journal box 17 and extends upward above the rail of thevessel. It has secured on its end the hand wheel 18. It can thus bereadily seen that by turning the wheel 18 the float will be revolved ina plane parallel with. the length of the vessel. Fig. 1 shows in dottedlines one float revolved to the opposite side. It may be undesirable torevolve the float too far downwardly, for in small craft there might bedanger of their capsizing. I therefore provide stops 19 to arrest themotion downwardly.

Fig. 4 is a similar construction as that already described. but themechanism is placed on the inside of the craft. It is here neces sary toextend the shaft 10 through the side of the vessel in order to securethe arm 4 thereon. This construction gives a better chance to man thewheel 18. More of its periphery is within reach and thus where occasionrequires more than one man may assist in turning it. The mechanism isalso more protected from accidental shocks and from the water.

Figs. 5 and 6 show a different construction. Here the float B is capableof being operated to both swing in a vertical plane as in theconstruction already described and also to swing in a horizontal planeto and from the vessel. A combination'of these motions permits placingthe float in a greater variety of positions and throwing it away fromthe sides of the vessel to make it more effective. The

following mechanism is employed for obtaining these results :The float Bis fastened rigidly to a spider 20 as by rivets 21. The spider has asocket 22 formed on it for receiving the end of the arm 23 to permit itto turn thereon. Any other manner of securing the float would do equallyas well, for instance, the universal joint already described maybe usedif desired. On the end of arm 23 is formed a hub 24. This is securedupon a shaft 25 mounted in a journal box .26 formed in a housing 27.Upon the shaft and within the housing is secured a gear 28. This gear isin mesh with a worm 29 secured within the housing upon a vertical shaft30. This shaft has its ends extending through the housing and on theupper end is secured the hand wheel 31. Thus far the mechanism issimilar to that previously described and by turning the hand wheel thefloat will revolve in similar manner. To obtain the second motion of thefloat, the housing instead of being rigidly secured to the vessel ismounted toturn upon a vertical axis. To accomplish this a bracket 32 isrigidly secured to the side of the vessel A as by bolts 33. The brackethas projecting therefrom the two extensions 3 1-34, within which snuglysets the housing 12. The shaft 30 is mounted to revolve through holesformed in the extensions 34 and is relied upon to retain the housing inplace and permit it to be revolved. The hand wheel 31 is convenientlyabove the railing of the vessel to facilitate an easy operation thereof,as in the construction previously described. To make it feasible to turnthe housing 27 a series of gear teeth 35 is formed on the outside of thehousing. These teeth are in mesh with a horizontal worm 36 secured uponone end of a shaft37. I The shaft .is .journaled in a sleeve 38 formedin the bracket 32. The sleeve and shaft extend through the side of theVessel, and a hand wheel 39 ismounted on the endof the shaft. It willclearly be seen that by turning the wheel 39 the float. will be turnedin a horizontal plane as shown in broken lines in Fig. 5. Andby turningthe Wheel 31 the. float will be turned in a vertical plane.

Fig. 8 is similar in construction to Fig. 4 with the exception that adifferently shaped float .D is shown. This floatdoes not consume thespace that a spherical float does.

Any shaped float may be used however that is desired.

A craft may be required with any number of my floats and of any desiredsize. When emergency requires it is intended that each float will bemanned by the requisite number of hands. The men will get their ordersfrom a single central source as from the oflicer on the bridge. For thispurpose each float will be specifically designated as by a number,letter or otherwise. In this way each float may be separatelymanipulated, to raise or lower it or swing it out or draw it in as theoccasion requires. For instance, if the vessel should spring a leak nearthe bow on the starboard side and below the water line, the men managingthe floats near that point would receive orders to lower the floats andthus raise that side, while the men at the other floats would receiveorders to raise their floats so that the vessel could take the necessarytilt to bring the leak above water. When a damaged part has been thusraised the craft may put into port or the damaged part being above waterand easily accessible may be repaired at sea. My invention enables acraft 011 fire to be scuttled and yet to keep afloat. In times of stormthe floats may all be set in uniform positions and the craft thus helpedto weather the storm. The floats are comparatively light, being watertight and only filled with air. When not in use they may be raised abovethe water level. I

Having thus described my invention I claim 1. In combination with avessel, floats, each comprising a water-tight shell, an arm secured atone end to the shell to permit the shell to turn thereon, a housingsecured to the side of thevessel, a shaft mounted in said housing forreceiving the other end of the arm, a gear mounted on said shaft withinthe housing, a worm in mesh with said gear, a second shaft mounted insaid housing for receiving the worm, and a hand wheel mounted on thesaid second shaft to operate the worm and gear to swing the shell todesired position relative to the vessel.
